Light & Irradiation

LED Driver

A power supply for an LED application needs to provide the semiconductor’s threshold voltage - but beyond that, the actual current flowing through the LED will determine its light output. LED drivers are DC/DC converter modules with a regulated output current to enable control of the LED’s brightness.

Short Introduction to Light & Irradiation

Whether you're developing industrial lighting, UV curing systems, biometric devices, or horticulture solutions, LED-based lighting offers the most efficient and reliable approach. In addition to a wide range of LEDs, this overview includes circuit solutions for driving and regulating current, ensuring precise brightness control tailored to your application’s needs.

The CRI (Color Rendering Index) is a measure of color rendering under artificial lighting and depends on the light temperature in Kelvin.


Plant lighting with horticulture LEDs: With suitable light recipes, plant growth can be influenced in the different growth phases.


Part of the online simulation platform RedExpert is the so-called Horticulator. With the Horticulator, individual light recipes can be utilized.


The difference between LED and laser: Lasers operate with stimulated emission, while LEDs rely on spontaneous emission. On the left is the light distribution of a VCSEL-type laser. On the right is the typical light distribution of an LED.


Monochromatic ceramic LEDs: Light intensity for different viewing angles. Besides the viewing angle, color also plays an important role.
